Eb prometheus

The prometheus scale is Scriabin's mystic chord laid out as a six note scale: root, 2nd, major 3rd, raised 4th, 6th, flat 7th. It is the lydian dominant sound with the 5th removed, which unmoors it: bright, whole-tone leaning and never quite resolving. Use it over 7#11 or 13#11 chords, or for harmonically suspended interludes.

it consists of these notes and degrees:

tip
  • This is the mystic chord as a scale: stack it in 4ths from Eb (root, #IV (A), bVII (Db), III, VI, II) to hear it as Scriabin voiced it.
  • Over a 13#11 chord, every note lands; with no 5th in the scale, nothing anchors, which is exactly the floating effect.
  • Treat II and VI as melodic pivots between the whole-tone-flavored lower notes and the dominant color of bVII (Db).
  • Resolve by half step: #IV (A) up to the 5th of the next chord, or bVII (Db) down to its 3rd; the scale exits gracefully despite its float.

How to play E♭ prometheus on guitar

Fret 1 on the D string carries the closest root, so melodies can start low even though the E-string barre sits way up at fret 11. A capo at fret 1 flips the key into D fingering, which lets familiar D-position grips take over. Open A and open G hold scale tones, an augmented fourth and a major third above Eb. Position one stretches clear out to fret 15.
